Build Order
- A capacity preserves the primary Model A strengths.
- D opposite preserves the central Model A counterweight.
- B auxiliary and C contributive complete the radial layer.
- Markers resolve the broad aspects into exact monadic elements.
Model L Practice
Drill the base values, capacities, sub-variant rules, and naming conventions until the cross becomes readable.
This is a focused practice space for the learning path. It tests the logic of derivation rather than drawing from the full TetraTypes quiz bank.
Study Companion
Start with base values, then move into capacities and sub-variant rules. Mixed drill is best once the codes are beginning to feel familiar.
Guided Cross Builder
Choose the four base values, then build the cross in stages: A capacity, D opposite, B auxiliary, C contributive, and finally the exact monadic markers.
Markers appear after the final stage, so the learner sees the structure before the exact notation.
Practice Drill
Each run shuffles the selected question set. Derive This Type asks you to connect base values, A-capacity, D-capacity, and exact monadic placement for all 16 TIMs.
